' Application filed Au ust 12,1908. Serial No. 448,242.

To all whom-ii my Be it known that I,W1LLIAM.L. DE Burma, a citizen of the United States,- residing at Chicago, in the county of Cook and State of 5 Illino1s', have invented certain new and useful Improvements in Tie-Plates, of which 'the following is a specification.

My invention relates to atie-plate as used by railroads for supporting the rails upon a tie, and the object thereo is to producea simple, efficient and durable plate of this character. Besides the advantages named, my tie-plate posses'sesthe additional advantage of lightness without the sacrifice of strength and rigidity, and is also of such formationv that it can be economically rolled. Moreover, my tie plate affords continuous support for the rail and at the same time provides ooves or recesses to drain away water an sand from between the tie-plate and rail.

The various features of advantage and utility in my new tie-plate will be apparent from the description hereinafter given.

In the accompanying drawing, Figure 1 is an edge View of my t1e-plate,Fig. 2 a plan.

view thereof, Fig. 3' an edge view of a modified form of plate, and Fig. 4 a plan view thereof.

Referring to the present embodiment of my invention as herein shown, the tie-plate 1, which in practice is rolled, is formed with a 'series of diagonal grooves or depressions 2 of suitable number and located between the continuous rail-supporting surfaces 3 and 4 extending from side'to side of the tie-plate in the direction of therail. These grooves are formed by or between the correspondingly. diagonal ribs 5 whose flattened and 40 sbmewhat extended tops form bearing or supporting surfaces for the rail, the same being on the same plane as the said surfaces 3 and fl, as clearly shown in Fi 1. These ribs by preference have beveled edges for ease of rolling or manufacture but may have straight or actual edges.

The grooves 2 merely extend between the continuous supporting surfaces 3 and 4 and are connected at their alternate ends owing to the staggered relationshi of the ribs 5 inasmuch as the latter are ree at one end and alternately connected at the other end totheir continuous supporting surfacesrespeetively, as clearly indicated in Fig. 2.

. 5 The tie-plate is further provided on its upper face'with a shoulder 6 along one side of the continuous supporting surface" against one side 0 its lower face with a pluralityjo the rail flange, aiid onges triangular in cross-section to' 'en gage the. tie and located in the present'instance im'mediately below the said continu'ous supporting surfaces 3 and 4, and extending in the same direction.

As shown, the ends of the tie-plate at 1" and 1 are by preference formed thinner so as to give considerable hearing or footingupon the tie with minimum amount of metal- As usual, the tie plate is provided with'the spike openings or holes 8 which may be square to receive the usual square section."

spike or round to receive the screw spike now coming into use.

By preference, these holes are surrounded by the bosses 9 whichext'end" .suflicientlyhigh to afford substantial backing" or support for the spikes.

Inthe particular form oftie-plate abovedescribed, the ribs 5 connect at one of their ends with the rail supporting surfaces 3 or 4 However, some measure ofmy invention may be obtained by-omitting such connection' but leaving the ribs and consequently the grooves diagonal and located between said surfaces. I have illustrated: such modified form of tie-plate in Figs. 3 and 4;, in

greatest over provides the grooves necessary for drainage of water and sand from between the tie-plate and rail, while at the same time giving ample rail-supporting surface, part of which is continuous fi'om side to-slde of Furthermore, the formation of the plate.

the tie-plate is such that it may be easily and conveniently rolled from the metal.

I claim:

1. A tie-plate having two continuous surfaces of substantially uniform width for supporting the opposite edges of the rail,-and-a series of grooves exten ing between and at an angle to but not penetrating said surfaces; substantially as described.

2. A tie-plate having two continuous' railsup tween and at an angle to but not penetrating said surfaces and formed betweenribs whose top surfaces are on the same plane as said surfaces and also constitute rail-supporting surfaces; substantially as described.

3. A tie-plate having two continuous railsupporting surfaces, and a series of grooves extending between and at an angle to said surfaces, the ends of said grooves beingformed by the inner sides of said surfaces; substantially as described.

4. A tie-plate having supporting surfaces, and a series of grooves extending diagonally and formed between diagonal ribs whose top surfaces constitute rail-supporting surfaces, the ends of said grooves being formed by the inner sides of said surfaces; substantially as described.

5. A tie-plate having on its upper side continuous parallel rail-su porting surfaces,

and a series of diagonal ri slocated betweeii said surfaces, said ribs being beveled; substantially as described.

6. A tie-,plate havingon its upper side a series of ribs forming a railsup ort and on its underside a series of depen ing flanges extending at an angle to said ribs; substantially as described.

7. A tie-plate having on extending between and at an angle to said surfaces and formed between ribs which are connected at their alternate ends to said surfaces; substantially as described.

ortin surfaces of substantially uniform two continuous rail-' between said surfaces its upper surface a series of grooves connected at their alters nate ends; substantially 8. A tie plate having twocontinuous rail- 9. A tie-plate having two continuous railsupporting surfaces, and a series of grooves extending diagonally between said surfaces and formed between diagonal ribs which are connected at their alternate ends to said surfaces respectively; substantially as described. 4

10. A tie-plate having on one side parallel continuous rail-supporting surfaces of substantially uniform width and a series of grooves extending between and at an angle to but not penetrating said surfaces, and having parallel flanges projecting from the other side ofthe plate; scribed.

and parallel flanges on the other side of the v plate, which flanges are arranged below the said surfaces; substantially as described.

12. A tie-plate 1 having on one side a series of diagonal grooves 2 connected at their alternate ends and formed between the diagonal ribs 5, bearing surfaces 3 and 4 for the rail, the ribs being connected at one of their ends alternately with said surfaces respectively, and flanges 7 on the other side of the late; substantialfy as described.

13. tie-plate having on' its upper side parallel rail-supporting surfaces, grpoves located between said surfaces, spike openings at the sides of said surfaces and bosses located at said holes to form a support for'the spikes; substantially as described. l
